They can range in size from just a few inches tall to more than 12 feet in the case of the tree ferns. Some types of ferns are tropical. Others quite hardy. Their versatility aside, ferns are valuable in the home and garden because they prefer shade. In the landscape, ferns bring fresh green life to those hard-to-design dim corners.
Prokaryotic cells have various shapes; the four basic shapes are: Cocci - spherical Bacilli - rod shaped Spirochaete - spiral shaped Vibrio - comma shaped.
  Prokaryotic Cells are cells that have to have organelles that are not surrounded by a membrane and do have ribosomes. Their DNA is in the shape of a circle. They have no â¦ nucleus, the DNA is bunched up in the cytoplasm. The type of cells that are prokaryotic are bacteria and only bacteria cells.   A prokaryotic cell is by definition a cell that lacks a membrane-bound nucleus. In addition, they do not have other membrane-bound organelles such as the endop â¦ lasmic reticulum (smooth or rough) or the Golgi apparatus.
